Quad Robocat 270

[Lillyryan]

Just built a Robocat 270. Nice build. Running Emax 2204 motors and 12 amp esc, Naze 32, Eachine ET200R VTR,
Sony 639 700 TVL cam. Using Cleanflight. Love this quad. Just have a slight wobble on descent so am I correct in thinking this is to do with the I gain?

Thanks Chaps

This is known as "Vortex Ring State" and is caused by the props sucking in dirty air which is has already pushed though. There are a couple things you can do to try and fix the wobble. First is set your quad to have an idle. Meaning set it where the props are spinning at low stick. This will help to keep from killing the quad in the air. Second, as you stated, increase your I gain. This should help significantly reduce the wobble. Don't do what others are suggesting and that is turn inverted and drive it to the ground lol. I have been seeing a lot of that lately.
